Convenient, big, fast, strong, easy to use. It has two compartments which can be used together or separately. In the compartments of low possibility to sterilize 6 330ml bottles of any shape. In the upper compartment to nipples, caps, bottle caps, pacifiers .... Versatility because we also put some accessories pump. Take little space in proportion to its capacity. Fast and safe, it sterilises in 6 minutes and turns off automatically. I recommend it except for the price that I find very high at least to come across a good promotion.
